Description

Röhrentrockner für Braunkohle Es ist bei Röhrentrocknern bekannt, an der Beschickungsseite in die Stirn der Einzelrohre :eine-Ein.fallkapsel einzusetzen, die einen Ouerstaib aufweist, um die .Öffnungen der Einzelrohre in zwei ,gleiche Hälften zu unterteilen. Der Zweck dieser Maßnahme ist, daß in das Innere der Rohrre nicht zu große Kohlenstücke gelangen, (die das Rohr zusetzen und dadurch leicht Anlaß zu Bränden oder Explosionen geben.Tube dryer for lignite It is known for tube dryers on the loading side in the face of the individual tubes: insert a drop-in capsule, which has an Ouerstaib to the .openings of the individual tubes in two, the same Divide halves. The purpose of this measure is that into the interior of the Rohrre not too large pieces of coal reach (which clog the pipe and thus easily Give rise to fire or explosion.

Demgegenüber soll nach der Erfindung noch eine Erhöhung des Durchsatzes von herab:zutrocknender Rohbraunkohle dadurch erreicht werden, idaß die Einfallkapisel eine zur Längsachse der Rohre geneigte Schaufel aufweist.In contrast, according to the invention, an increase in throughput is also intended from down: raw lignite to be dried can be reached by the fact that the collapsible capsule has a blade inclined to the longitudinal axis of the tubes.

Eine weitere Ausgestaltung der Erfindung besteht .darin, da: die Schaufel nicht nur geneigt, sondern auch noch schräg zur Längsachse der Einzelrohre angeordnet ist. Eine ,derartig angeordnete Schaufel wirkt gewissermaßen als Förderschnecke -und fördert Idas in die Rohre hineingelangte Trodeemgut schneller weiter, wodurch neuer Raum für nachfallende Kohle frei wird.Another embodiment of the invention consists in that: the shovel not only inclined, but also arranged obliquely to the longitudinal axis of the individual tubes is. A shovel arranged in this way acts to a certain extent as a screw conveyor -and conveys Idas trodeem that has got into the pipes faster, which means new space for falling coal becomes available.

Mit Vorteil ist bei (beiden Vorschlägen die Schaufel derart in die Einfallkapsel eirngesetzt, daß ihre vordere Kante und die Vorderkante der Einfallkapsel in einer Ebene liegen.With both proposals, it is advantageous to insert the shovel into the Collapse capsule set that its leading edge and the leading edge of the collapse capsule lie in one plane.

In -der Zeichnung ist das Wesen der Erfindung an zwei Ausführungsbeispielen, und zwar in Stirnansicht und Schnittdargestellt.In the drawing, the essence of the invention is based on two exemplary embodiments, namely shown in front view and section.

Gemäß Abb. i weist die Einfällkapsel i, deren Längsenden 2 frei sind, so daß sie durch Federung @an die Innenflächen der Trockenrohre angedrückt werden, eine schräg zur Längsachse des Rohres angeordnete Schaufel 3 ,auf. Die Vorderkante 4 dier Schaufel 3 liegt zweckmäßig mit der Vorderkante der Einfallkapsel i in gleicher Ebene, um eine besonrders günstige Schaufebwirkurng zu erreichen.According to Fig. I, the precipitation capsule i, the longitudinal ends 2 of which are free, so that they are pressed against the inner surfaces of the drying tubes by springing, a blade 3 arranged at an angle to the longitudinal axis of the pipe. The leading edge 4 dier blade 3 is expediently with the front edge of the capsule i in the same Level in order to achieve a particularly favorable display effect.

In der Abb. 2 isst die Sehaufel 3 nicht nur geneigt, sondern auch noch schräg zur Längsachse deis Einzelrohres angeordnet. Die Schaufel 3 wirkt hier gewissermaßen wie eine Förderschnecke.In Fig. 2 the scoop 3 not only eats inclined, but also still arranged obliquely to the longitudinal axis of the individual tube. The blade 3 acts here like a screw conveyor, so to speak.
